Overkill, even a 1MHz will do. Get a portable, like this one: http://www.seeedstudio.com/depot/dso...a4dfe423fcc11a

Agreed w/ Rev- 1 Mhz is child's play.

That said, I don't like the one he linked to, as it's only a single channel. For automotive work, it's nice to have at least 2 channels so that you can look at the relationship between two events, such as the relationship between CKP and CMP, or between CMP and an injector or ignition output, etc.

The scope you linked to would work fine. Personally, I've become spoiled by having a USB scope. Nice to be able to save traces to the hard drive. This is a newer model of the one I bought a few years ago: http://cgi.ebay.com/Hantek-DSO-2250-...ht_4889wt_1139

Delta fails at generating form letters.

Got this in my email this morning:



Now, I don't know what a 10000624 is, or why Mr. Broberg thinks that I was subjected to one while aboard Delta Flight 0 eleven years ago. Actually, I remember exactly where I was on 1 Jan 2000- working at the Harris plant in Mason, OH. I remember this by way of the fact that I was so damn tired from having done precisely the same thing the day before that I slept right through the 1999-2000 tickover.

Quick question: If I tune my car for E85 and want to switch back and forth between 91 and E85, will I have to drain the tank going from E85 -> 91? I know I will when I go from 91-> E85, but what about from E85 to 91? EDIT: I guess the real question is wheather or not I can switch to 91 with like 1/4 to 1/8th a tank.

I turned on my car this morning and "Turbo Lover" by Judas Priest was on the radio. I think this is a sign my car wants to take this to the next level. Time to start squirtin'.

Do you have an ECU that can measure the blend and interpolate the dual maps appropriately?

I've wondered about this. How does that feature work? Fuel tank sensor? How does it measure octane in unburned, liquid fuel?

I have a laptop in the car with me every time it is driven - switching maps on the go isn't too much work, I've done it before. If not, I just make do with whatever map is currently loaded.

you use a flex fuel sensor: http://www.megamanual.com/flexfuel.htm

Yeah, but I think his question (and I want to know too) is how exactly do these things actually work? What is the mechanism by which they judge the composition of the fuel? Do they run it between two plates and measure the effective capacitance? Do they pass it through a chamber containing a small amount of americium-241 and measure the rate at which some element in the fuel bonds with the ionized nitrogen atoms generated by the slow alpha decay of the source? Do they use it to lubricate a tiny pink ***** and have a tiny little man constantly describe the relative lubricity as the ***** is repeatedly inserted and withdrawn from his tiny little anus?

In a "proper" blended fuel setup, the aforementioned sensor acts as a variable correction to the tables. It's not simply switching from one to another at some predetermined point, it's more of an analog phenomenon. The correction which is applied varies by the proportion of the contents of the tank which grew on a tree vs. being sucked out of a rock.

Could you get away with table switching if you always took it down to 1/8 tank before switching to the other fuel? Probably. Your ignition map for E85 would need to be more conservative than usual, and gEGO would certainly get a workout. The tendency would be for the system to run rich when switching from E10 to E85, and lean when switching in the reverse direction.
